> Currently Hive+Parquet doesn't support it. It should include at least basic type promotions
short->int->bigint,  float->double etc, that are already supported for  other file
formats.
> There were similar effort (Hive-6784) but was not committed. This JIRA is to address
the same in different way with little (no) performance impact.
